3.1

Interrupt power supply using battery disconnect switch

Only vehicles with battery disconnect switch.

 Danger!

Risk of explosion caused by escaping oxyhydrogen gas. Risk of injury caused by caustic burns to eyes, skin and mucous membranes from battery electrolyte (contains diluted sulfuric acid) or metal spatter due to short circuit. Risk of burn injuries caused by short circuit. Risk of poisoning caused by swallowing battery electrolyte (contains diluted sulfuric acid) or absorption of lead over the skin or orifices

No fire, sparks, open flames or smoking.

Wear acid-resistant gloves and clothing and safety glasses with side guards.

Do not place any conductive objects on the battery and avoid any short circuit from battery positive to ground.

Only fill liquid battery electrolyte (diluted sulfuric acid) into suitable and appropriately marked containers.
